Problem description when I was a university student ten years ago, China introduced some film blockbusters from abroad every year. One of the movies was called "the player's game" (English name: zathura ), until now, I have been impressed by some of the Computer stunts in the movie.
Today, we chose the computer test as a brave choice. In this short term, we are talking about the game topic. Therefore, now everyone is playing the "multiplayer game", which is why I name this question.
Of course, in addition to being brave, I also hope to see "integrity". No matter what the test scores are, what I want to see is a real result. I believe everyone can do it ~

What is the first game to be played by beginners? It is very simple. It is defined as follows:
1. This game is a two-person game;
2. There are a pile of stones with N in total;
3. Take turns;
4. Each step can take 1... M stones;
5. the first party to win the light stones;

If both sides of the game are using the best strategy, please output which one can win.

 

The input data first contains a positive integer c (C <= 100), indicating that there are group C test data.
Each group of test data occupies one row and contains two integers n and M (1 <= n, m <= 1000). For the meanings of N and M, see the topic description.

 

Output: if the first person wins, output "first"; otherwise, output "second". The output of each instance occupies one row.
